冷床是冶金軋鋼行業(yè)對軋制產(chǎn)品（螺紋鋼、園鋼、鋼管等）有效進(jìn)行冷卻的工作臺面。冷床由機(jī)械傳動系統(tǒng)、水冷卻系統(tǒng)、冷床工作臺面、固定支架等方面組成。冷床主要有拔齒式冷床、齒條步進(jìn)式冷床、撥爪式冷床、運(yùn)載鏈?zhǔn)嚼浯?、滾盤式冷床等。

The cooling bed is metallurgical industry of rolled products (steel, steel, steel and other garden) effectively cooling the work surface. The cooling bed by mechanical transmission system, water cooling system, cooling bed table, etc. of fixed bracket. The main bed tooth pulling type cooling bed, rack step type cooling bed, poking claw type cooling bed, carrier chain cooling bed, rolling disc cooling bed etc.

首先確定所需壓力的大小，主要取決于以下幾方面：被矯鋼材的品種、規(guī)格；待矯軋件的原始彎曲程度；待矯軋件的終軋溫度；被矯軋件的機(jī)械性能；矯直溫度等。

First, determine the size of the required pressure, which mainly depends on the following aspects: the varieties and specificati of the straightened steel, the original bending degree of the rolled piece, the finishing temperature of the rolled piece, the mechanical properties of the leveled piece, the straightening temperature and so on.

中型軋鋼車間生產(chǎn)的各種鋼材，經(jīng)軋鋼機(jī)軋制后由熱鋸機(jī)（或剪切機(jī)），切成定尺長度，還需要冷卻到常溫，再進(jìn)行矯直。軋制后的熱軋件冷卻時，由于連續(xù)生產(chǎn)，一般都是在緩慢的橫向移動過程中逐漸冷卻的。這種使軋件橫向移動并冷卻的設(shè)備，叫做冷床。

All kinds of steel produced in medium rolling mill are cut by hot saw (or shearing machine) after rolling mill, and it is cut into length of fixed length. It also needs to be cooled to normal temperature and then straightened. After rolling, the hot rolled parts are cooled down gradually because of continuous production. The equipment for rolling and cooling the workpiece is called cold bed.
